Higgs TTS

Higgs TTS is an online AI voice generator that converts written text into natural, expressive speech in over 100 languages. Users can select voice characteristics like gender, age, accent, style, and speed, and download the audio directly in the browser. The platform also offers zero-shot voice cloning, which uses a short 3–30s reference clip to make the model speak new text in a chosen voice across multiple languages.

New accounts receive three free credits to start generating audio without any upfront cost. These credits never expire, and additional credits can be purchased in packs that also do not expire. The service operates entirely within the browser, requiring no installation or a dedicated GPU to run.

Pricing is based on generated text length, with one credit equaling approximately 100 characters. The entry pack costs $9.90 for 800 credits, while the most popular pack is $29.90 for 3,000 credits. All credit packs unlock the full set of voice controls and features without any premium voice tier surcharges.

The Higgs Audio v3 TTS engine powers the text-to-speech and voice cloning features, allowing users to direct the voice by choosing gender, age, accent, style, and pace. This dedicated tool provides a larger workspace for longer scripts compared to the standard quick preview mode.

Users can generate audio in over 100 languages using the same balance without needing separate plans or per-language add-ons. The system handles both standard text-to-speech and zero-shot voice cloning at the same per-character rate across all accents and styles.

The Refund Policy states that paid credit purchases are generally non-refundable once any credits from that purchase have been used. A refund may be requested within 7 days of purchase if none of the paid credits have been used and the account is not involved in abuse or fraud.

Generated audio files remain accessible in the user's library for six months, allowing them to return to download or reuse the content later. This six-month retention period applies to all generations regardless of the voice or language selected.

The service supports zero-shot voice cloning, which requires uploading a short 3–30s reference clip to confirm consent before the model speaks new text in that voice. This feature allows users to clone a voice even across different languages without needing extensive training data.

Some users on Reddit mention Yvette avatar v0.3 as a local voice-avatar alternative that runs entirely on a user's own PC, contrasting with Higgs TTS which operates in the browser. While Yvette is a separate local tool, Higgs TTS focuses on browser-based generation without local hardware requirements.

The platform is designed for anyone needing quick caption reads, long-form narration passes, or voice cloning runs from a reference clip. It handles short tests and larger production batches within the same browser workspace without a separate app.

Higgs TTS is an independent AI tool that is not affiliated with, endorsed by, or sponsored by any third-party model provider. The website explicitly states that all product names and trademarks belong to their respective owners.

The website mentions Seedance 2.5 and Seedance as underlying technologies or models used in the generation process. These names appear in the footer alongside the main Higgs TTS branding.
